a. Explanation Given data: The gun is fired at an angle ( θ ) is 40 ° . The initial velocity of T-shirt ( v i ) is 28 m s . The horizontal distance of fan from the gun ( X f ) is 60 m. Formula used: Formula for horizontal component of initial velocity as follows. ( v x ) i = v i cos θ (1) Here, v i is the initial velocity, θ is the gun fired angle. Formula for vertical component of initial velocity as follows, ( v y ) i = v i sin θ (2) Kinematic equation formula for the horizontal position as follows, x f = x i + ( v x ) i Δ t . (3) Here, x i is the initial horizontal distance, Δ t is the time interval. Substitute 0 m for x i in equation (3), we get x f = ( v x ) i Δ t (4) Explanation: Figure 1 shows an air gun fires T-shirt. The problem is about projectile motion with the initial velocity at an angle above the horizontal. This means that, both the vertical and horizontal components of the initial velocity are present. Substitute 28 m s for v i , and 40 ° for θ in equation (1) to find horizontal component of initial velocity b. To determine To choose: The correct option from the given options.
